Ac does not kick on at all

Passenger fuse box left kick panel, driver side. The kick panel goes from the floor up to dash. There is also, a fuse box under the hood.

many cars automatically kick on the air compressor in defrost, to dehumidify the cabin air

not sure where the fuse is for sure either under hood or drivers side under dash,but if the refrigerant gets low as it will over time or if theres a leak the ac clutch will not kick in. even with heat on defrost the ac clutch should kick in and out if ts working proper

the cab heater fan?, there can be 4 fans on some cars.
front condenser, 2 on rad, and 1 in cab heater box.
the cab fan? does it fail on high too?
it has a switch, (marked fan speed)
the switch is bad ,if low speed are dead. and high are good.
or wiring to it , the motor or the fuse.
even a cracked fuse, change the fan fuse to a new fuse.

The problem is either an actuator or the door associated with it. Sometimes the gear strips, especially when the system goes thru a recalibrate after power has been removed and reapplied. Below is a diagram of the locations of the actuators.

GOOD LORD,, Not here to knock any ones work but.. could be many things.. I guess you checked all fuses.. sounds like fuseable link didn't like being wired around.. I would make sure acc. wire is not missing from battery. check pressure switch wires at the dryer see if you have fire with switch on if not run hot wire and see if air comp kicks on .. do you have power to air cond fuses .. bet you dont.. fuseable link or check relays fuseable link didn't like that wire around.. hard to tell you where to start.. need someone to undo what he did i would call Better Business Bereau. I could coach you threw this repair but we would have to have better communication..

You may have a problem with your AC compressor if the bearings are bad they can rob a lot of power from your engine.

Fuses are in the kick panel on the passenger side. If it blows again, you will need to find the malfunction (don't put in a higher rated fuse) Most times the blower motor will cause fuse failure as when the motor gets older it begins to draw excessive amperage...but don't change it till it is actually verified as being bad.

Try looking under the hood. There should be a power control unit with fuses and relays that control the AC. If you suspect it is a relay take on from another source that isnt detimental to the operation of the engine and swap it over. If your AC starts to work then that is your problem.

ac fan fuse should be in engine comprtment in a labled box near firewall passenger side
